The wait to see the doctor is my only complaint. She is otherwise friendly, knowledgeable, takes the time to listen to you and explains things extremely well. I think she is very competent but I still waited over one year to see her and I made my next visit with her exactly one year in advance. I could have had zoom visits with her but I prefer to actually meet & see the doctor.
